Tubing connection

• Detach the valve cover of outdoor unit.
• Align flaring nut to the thread center, and
screw the nut tightly by hand.
• Screw tightly the flaring nut with torque
spanner until the torque spanner produces
"click" sound.
• It is recommended to use torque spanner to
connect the tubing. If other flexible or fixed
spanner is used, it may damage the horn
mouth due to improper force.
• The bending angle of the tube should not be
too small or the tube may break up, so the
service personnel should use tube bender to
bend the tube.
• Never let water, dust or sand gets into the
pipe.
